Absolutley not.... Pretty sure it says right on the can not to.... And those 4inch 90 degree elbows are not pressure rated. Neither is the bell reducer, or the end cap.... The only thing pressure rated on that cannon is the ball valve... Dismantle it before you kill yourself.....

Look at the elbow you used and posted then look at the ones Dewey posted. See the difference??? Your fittings must say nsf/pw on them. If they do not, then do not use them. Cant get any easier than that. Also if they say DWV like they do on your cannon, do not use them..

Are you serious???? Does it really matter???? Just as far as a grenade!!! I would be more worried about those DWV elbows you are using. If you even look at those things the wrong way they break. :laughing3:

It could shatter at 20 psi...Make a new cannon dude. Re use the 4 inch for a cheap o conbustion cannon or a barrel. Also not one of your fittings are pressure rated either... Is losing a eye or killing yourself worth it??? Start over from scratch!!!!

Good job, I love the golf ball cannon. However you could increase performance if you cut down on pilot volume.
